What is the difference in function between basophils and eosinophils? What is meant by tissue regeneration? Fibrosis, also known as fibrotic scarring, is a pathological wound healing in which connective tissue replaces normal parenchymal tissue to the extent that it goes unchecked, leading to considerable tissue remodelling and the formation of permanent scar tissue. 2020 Nov;2(11):1350-1367. doi: 10.1038/s42255-020-00306-2.

This result shows that when the kinetic energy K of the incident proton is large compared with its rest energy $m_{p} c^{2},$ then M approaches $\left(2 m_{p} K\right)^{1 / 2} / c .$ Therefore, if the energy of the incoming proton is increased by a factor of 9, the mass you can create increases only by a factor of 3, not by a factor of 9 as would be expected.
